1. A deep-UV optical frequency comb at 205 nm
Topic: Optical Physics
Published: 5/25/2009
Authors: Scott A Diddams, E Peters, P Fendel, S Reinhardt, T W Hansch, T Udem
Abstract: By frequency quadrupling a picosecond pulse train from a Ti:sapphire laser at 820 nm we generate a frequency comb at 205 nm with nearly bandwidth-limited pulses. The nonlinear frequency conversion is accomplished by two successive frequency doubling ...

2. A versatile light-emitting-diode-based spectral response measurement system for photovoltaic device characterization
Topic: Optical Physics
Published: 6/29/2012
Authors: Behrang H Hamadani, John F Roller, Brian P Dougherty, Howard W Yoon
Abstract: An absolute differential spectral response measurement system for solar cells is presented. The system couples an array of light emitting diodes (LEDs) with an optical waveguide to provide large area illumination. Two unique yet complementary measur ...

3. Adaptive measurements in nonorthogonal state discrimination
Topic: Optical Physics
Published: 12/18/2012
Authors: Francisco E. Becerra Chavez, Alan L Migdall
Abstract: Adaptive measurements represent important resources in quantum information science and quan- tum technologies. They take advantage of the knowledge of partial measurements of the system to optimize subsequent measurements and perform tasks that are ...

4. An Analysis of the Probability Distribution of Spectral Angle and Euclidean Distance in Hyperspectral Remote Sensing Using Microspectroscopy
Topic: Optical Physics
Published: 5/18/2013
Authors: Ronald Resmini, Christopher Deloye, David W Allen
Abstract: Determining the probability distribution of hyperspectral imagery (HSI) data and of the results of algorithms applied to those data, is critical to understanding algorithm performance and for establishing performance metrics such as probability o ...

5. Calibration of an Astrophysical Spectrograph below 1 m/s using a Laser Frequency Comb
Topic: Optical Physics
Published: 6/4/2012
Authors: David F Phillips, Alexander G Glenday, Chih-hao Li, Claire Elizabeth Cramer, Gabor Furesz, Guoquing Chang, Andrew Benedick, Li-Jin Chen, F X Kaertner, Sylvain G Korzennik, Dimitar Sasselov, Andrew Szentgyorgyi, Ronald L Walsworth
Abstract: We deployed two wavelength calibrators based on laser frequency combs (,astro-combsŠ) at an astronomical observatory. One astro-comb operated over a 100 nm band in the deep red ( 800 nm) and a second operated over a 20 nm band in the blue ( 400 nm) ...

6. Computational Parameters in Simulation of Microscope Images
Topic: Optical Physics
Published: 11/28/2008
Authors: Egon Marx, James Edward Potzick
Abstract: The simulation of microscope images computed from scattered fields determined using integral equations depend on a number of parameters that are not related to the scatterer or to the microscope but are choices made for the computation method. The ...

7. Demonstration of Superluminal Images
Topic: Optical Physics
Published: 6/19/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: Optical pulse propagation with group velocities larger than the speed of light in vacuum, c, or negative, have been demonstrated theoretically and experimentally in a variety of systems [1‹5]. The anomalous dispersion required for generating ,fastŠ l ...

8. Digital Phantoms Generated by Spectral and Spatial Light Modulators
Topic: Optical Physics
Published: 10/21/2015
Authors: Bonghwan B. Chon, Fuyuki Tokumasu, Ji Y. Lee, David W Allen, Joseph Paul Rice, Jeeseong Hwang
Abstract: A hyperspectral image projector (HIP) based on liquid crystal on silicon (LCoS) spatial light modulators (SLMs) is explained and demonstrated to generate 3D spectral data cubes. The HIP- constructed data cubes are 3D images of the spatial distribu ...

9. Dynamic light deflection in an active Raman-gain medium using a spatially inhomogeneous pump
Topic: Optical Physics
Published: 7/25/2013
Authors: Lu Deng, Edward W Hagley, Chengjie Zhu
Abstract: We study optical wave deflection in a three-level active Raman gain medium using a spatially inhomogeneous pump field. Using the eikonal approximation, we derive an analytical expression for the deflection angle and demonstrate more than an ord ...

10. Effect of atomic coherence on "temporal cloaking" in atomic vapors
Topic: Optical Physics
Published: 2/27/2013
Authors: Runbing Li, Lu Deng, Edward W Hagley, Joshua C Bienfang, M G Payne, Mo-Lin Ge
Abstract: We discuss a different scheme to achieve temporal cloaking in warm atomic vapors. Instead of creating a temporal-spatial window in a patched broadband short optical pulse using static differential dispersion of an optical fiber, we create a tempo ...
